In December of last year we brought you a baseline MAHA dyno of the new F10 M5 by PP-Performance. PP-Performance has now finished their Stage I F10 M5 tune and the result is 492 at the wheels or corrected out by the dyno to 617 horsepower at the crank. Compared to the baseline dyno this is a gain of 48 horsepower at the rear wheels and 54.1 at the crank. Once the dyno corrects the numbers for the weather conditions the gain stated at the crank is 44 horsepower. It seems we are looking at a gain around the 50 horsepower range for a Stage I tune on the F10 M5.

So it could potentially do over 500 to the wheels with a simple tune... amazing vehicle! I would also like to see a few bolt ons, perhaps straight pipes for experiment sakes as well as a meth kit... Does anyone have any idea if this dyno reads low/high?
